This method is provided to enable a program to check whether a connection
between two objects (represented by one object holding a moniker that identifies
the other) is up-to-date. For example, if one object is holding cached
information about the other object, this method can be used to check whether the object
has been modified since the cache was last updated. See IMoniker::GetTimeOfLastChange.

Notes to Callers

If you're a moniker provider (that is, you hand out monikers identifying your
objects to make them accessible to others), you must call the IRunningObjectTable::NoteChangeTime method whenever your objects are modified. You must have previously called IRunningObjectTable::Register and stored the identifier returned by that method; you use that identifier
when calling IRunningObjectTable::NoteChangeTime.

The most common type of moniker provider is a compound-document link source.
This includes server applications that support linking to their documents (or
portions of a document) and container applications that support linking to
embeddings within their documents. Server applications that do not support linking
can also use the ROT to cooperate with container applications that support
linking to embeddings.

When an object is first registered in the ROT, the ROT records its last change
time as the value returned by calling IMoniker::GetTimeOfLastChange on the moniker being registered.
